Oidio Killer by Agrobacterias

Agrobacterias Oidio Killer is a natural, organic fungicide that can be used on both indoor and outdoor plants. Its formula, based on Bacillus amyloliquefaciens (formerly known as Bacillus subtilis) allows protection against different fungi such as powdery mildew, botrytis and downy mildew, among others.

The bacteria present in Oidio Killer secrete enzymes and other metabolites that inhibit fungal growth while stimulating the reinforcement of the plant's natural defenses. For that reason, this product can be used to both combat and prevent fungal attacks.

In addition to Bacillus amyloliquefaciens, Oidio Killer contains organic matter, amino acids and organic potassium, which help stimulate plant development and strengthen the leaf cuticle, enabling the plant to better resist stress, both biotic (caused by pests) and abiotic (caused by climate).

This product should be applied every 15 days for best results.

Characteristics of Oidio Killer:

  • Natural contact fungicide, highly effective against powdery mildew and botrytis.
  • Stimulates plant development

Dosage of Oidio Killer:
